Arrochar, stetlilslandi N- ma aw M 31 s N64! 553,763 1 This invention relates to new and useful. immovements in a. powder spray and injector. The inventionhas for an objectth'e' construction of a-powder spray and injectorintended particularly for spraying" an antiseptic," deodorizing powder into'ithe vagina. The spray and injector is to be particularlycharacterized by the ability of controlling the spraying streams. 1

.It is a still further object of this invention to construct a spray and injector which'has. a hollow head adapted to receive a:: cartridge of powder coaxially within a passage. for air ina manner so that when the air is passed along it will pass through the cartridge and cause spraye ing of the powder.

Furthermore, another one 6: the. objects of this invention is the inclusion of a spring dis posed over the discharge 'end of jthe' powder cartridge-for'the purpose of'breaking down. the" t y i "xzThe powder'cspr'ayand injector, according to powder into spray form. a i

- Another one of the object; fitl lis invention" is the construction and arrangement of mounting of the springin'its position for'breakingid'ow'n the and ofzthe object and advantagesthereof, refer once willfbe had to the following description iand to the appended claims in which'thevariousnovel featuresbfthe invention are more particularly setforth.

view taken on the line Fig. '7 is. a sectional view taken on the line Fig-'14 is a perspective View of the spring used this invention, compi'ises'i a' stemi-lu having Ia socket end-11" for connection with an air bulb 102 The Idetails of the air':-bulb are not'given since thebulbsare generally known; The socket ll isforhied withthreads 12 into which'the conhection'from the 5 air bulb i may be engaged.- At the other =:end,' it'he Tstem lO terminates in a 'conicaloportion" '13 which then connectsfwith a,

semi cylindrical portion 14." A peripheral'groove is for'medon' the tip Ioi' theconical portion 13 andc'onnects with-alongitudinal groove'16 upon a small cylindrical-portion 1'7 int'erposed between the conical portion 13 and the semi-cylindrical portion- 14. 'I'he air passagethrough the stem in an-openingj18inthe cylindrical portion 17. At the freee'nd, is completely cylindrical, indicated by. reference numeral 19. This complete cylindricalpor tion is only of very small witlthf Slid'ahly nmun'ted noon the cylindrical portion 19, the semi-cylindrical portion-14 of the cylindrical portion 17 is a casing 20. l Thiscasing' is of hollow construction and tapered 'of! at the front "21 into a point; An opening 22 is formediin'th'e front end. One side of the casingis formed. with-an openin 23 which is capable or aligning with'the' open side of the semi-cvl-ind'ricalv portion14. AtQtheIbase, the casing 204s formed with an inward depression 24 and terminates extension of the case." In the event that the case is completely e'x'tended'the depression 24 will act agalnstjthe bottom of the cylindrical portion 19 and prevent 'completeen5 gagement; When the casing '20 ismoved completely backuponits seat', the depression 24 is the semi-cylindrical portion '14.

I its closed position. It may be moved to an open I 16 and then into the peripheral groove 15. Upon turning of the parts relative to each other, the casing willbe latched in this condition.

The cylindrical portion 19 is formed with spaced peripheral grooves connected witha longitudinal groove 26. A, powder breaking spring 27 may be supported upon any of the peripheral grooves 25. This spring has .a portion 28- engageable through the slot 26 in a-ring portion 29 engageable in any of the grooves 25.

In Fig. 1 the casing member 20 is shown in position by rotating it to a position in which the open side 23 aligns with the openside of the semi-cylindrical member 14; This condition is, shown in Fig. 2. In this latter condition a car-l tridge of powder may be inserted therein. A detail of this cartridge is shown in Fig. 8 and comprises a cylindrical portion 30 and end caps 31.

end caps are removed when the cartridge is inserted in place within the device; After its insertion'through the opening in the condition of the parts shown in Fig. 2, the casing member 20 may be turned so that'the opening" is closed and.

me cartridgejis within. Squeezing ot the bulb will then cause the air to pass through the cartridge and operate the powder-from the aper-' ture 22. 1 The spring 2'7 causes breaking oi the powder so thatfit comes out ina fine spray.

In Figs. 11 and 12 a. modification of the invention has been disclosed in which the stem '10 connects with a barrel portion 32fhavi'ng a conical end 33 and'an open end 34. A head member 35 is threadedirengaBed .upon the free end 01' the.

hollow member 32. 'This head member has an opening 36 flirough which discharge takes place. I

A conical Spring is ,hmised within the conical portion 33 and acts against the bottom edge or the .SOte'ndin'g to eject the cartridge;

The cartridge isheld in place'by a spring'38.

The 'sprmg 38'has a hadportion 39 extended overthe end oi the cartridge '30 and theshank portion '40 engaged in a longitudinal slot within the cylindrical member 32. A projection 41 upon the stem portion 40 of thes'pring' is capable of engaging one ota series of semi-cylindrical reeeses 42 within the hollow member 32 so as to elect the murmur the spring relative to the r the inner conlcal'sides 43. of
